Maintenance engineers, superintendents and foremen can observe procedures performed in accordance with correct and efficient fundamentals. Road maintenance and repair work will last longer and available funds will go further. The course also discusses the appropriate materials, equipment and tools used in each maintenance activity.
Upon successful completion of this course, the delegates will be able to:
Common Maintenance Problems and Causes
Common maintenance problems occurring on pavement surfaces, road bases and sub-bases, earth and gravel roads, shoulders, drainage facilities, bridges and roadside, the main causes of most road maintenance problems
Traffic Control during Maintenance
Protection of maintenance workers and equipment, basic principles for selection, placement, maintenance and removal of traffic control devices, typical applications of traffic controls for maintenance works, International Road Signs
Pothole Repair in Asphalt Concrete Pavement
Potholes repair, procedure using proper materials, tools and equipment, the proper shaping of the repair and the compaction of the mix
Pothole Repair in Surface Treatment Pavement
Correct procedures for use of granular material for filling the pothole, proper equipment and materials used for repair, placing the traffic control devices, marking the damage area, cutting out and removing all damaged material, compacting the granular material, sealing the surface with liquid asphalt and cover aggregate, cleaning the work site and removing the traffic control devices
Crack Repair in Asphalt Pavement
Repair procedures for linear and alligator cracks from three to twelve millimeters wide, proper hand tools and equipment designed to do the job, materials for filling and sealing the cracks
Repair of Depressions, Rutting and Corrugations
The basic repair method for depressions, rutting and corrugations, the proper procedures to perform this repair method with a motorgrade, special considerations for placing and compacting each layer in a deep depression, how to place and compact a thin overlay over the leveling course
Base and Sub-base Repair
Correct procedures for the repair of base and sub-base, placing the traffic control devices, marking the limits of repair and cutting the pavement, removing all unsuitable material, installing required sub-drainage, restoring the sub-grade, replacing the sub-base and base, replacing the pavement surface, cleaning the work site and removing the traffic control devices
Single and Multiple Surface Treatments
Good construction practices, preparation of the surface to be treated, testing of the asphalt distributor, and checking the weather, materials required for surface treatments, proper procedures for applying the asphalt, spreading the aggregate and compacting the aggregate, construction of smooth transverse and longitudinal joints
Slurry Seal
Useful and cost-effective method of maintaining paved surfaces, resources needed to perform a slurry seal job including materials, equipment and manpower slurry seal operation steps: storage and loading of materials, traffic control, surface preparation, slurry application, curing, rolling and clean-up
Patching Unpaved Roads
Maintenance for repairing surface defects such as potholes, ruts, gullies and soft spots on unpaved roads, maintenance practices for preparing the hole, filling it with granular material and compacting the material are shown in detail
Smoothing and Reshaping of Earth and Gravel Roads
Smoothing, and reshaping: equipment requirement, overview of work steps, work step summary, considerations for planning and preparing for the work are treated, procedures for checking the road cross slope at straight and curved road sections
Regraveling
Necessary repairs of the road and drainage system before regraveling, equipment, materials, and procedures for regraveling: traffic control, reshaping and compacting the sub-grade, hauling and placing the granular material, and compacting the granular material. Methods for checking the road cross slope and quick testing of the material’s moisture content
